  1. Learning Target: Be able to describe the characteristics of emission and absorption spectra and understand basic spectroscopy and how it applies to Astronomy Kick off: How is spectroscopy used in astronomy? Vocabulary: Spectroscopy Spectroscope spectrograph Turn in Holiday Homework Check—bring me your logs Finish spectroscopy-notes and lab, turn in lab Reading pg. 77-81 then read the summary on pg 94 Answer review and discussion questions 1,2, and 3 in complete sentences. Describe Kirchoff’s laws. If time: Video on Telescopes Jan 8 and 9 Agenda
  2. Kirchoff’s law #1: Solids and liquids emit light of all wavelengths and are said to have a ________________________ of radiation. Kirchoff’s law 2 states that a __________________________________emits light whose emissions are characteristic of the gases chemical composition. Kirchoff’s third law states that a ______________________________leaves dark absorption lines. Radiation can be analyzed with an instrument known as a This is used in a spectroscope in place of a prism.
